## ssh tunneling cmdline
Setup the tunnel:

ssh -i <identity file for bastion> -L <localport>:<endpoint ip or name>:<endpoint ssh port or other port> <bastion user>@<ssh bastion server>


Then from local machine connect to local port which will be forwarded to endpoint

ssh -i <identity file for endpoint> <endpoint user>@localhost -p <localport from above>
